In order to insure a circulation of the hot vapors For this purpose there is shown a worm wheel l3 between the two shelves of each pair as they pass mounted on the shaft co-operating with the worm the open end of the flue 35, an inwardly and shaft l4 journalled in suitable brackets l5 seupwardly inclined deflector 36 is secured to a cured to the outer face of one of the walls of wall of the casing above the outlet of this flue. 2 the casing and to which shaft power may be Supplementing or displacing the deflector 36, an applied. outwardly projecting and downwardly inclined The reel, as shown, comprises a pair of spiders deflector plate 31 may be attached to the outer I6 and I1 fixedly mounted upon the shaft l2 and end of the upper shelf of each pair.

A stub shaft I8 is journalled parallel with the The several baking shelves are preferably of shaft l2 in the outer end of each of the reel uniform size and shape; those of each pair being arms, the bearing being, preferably, of the ball spaced apart sufficiently to permit the passage type, as shown at 19 in Fig. 3, this bearing being of the hot vapors between them.

When the shelves are in the posi- 5 tion as shown in Fig. 1, a portion of the hot vapors will enter between the lower shelf of the upper pair and the upper shelf of the lower pair, insuring the baking of the under side of the contents of the former and the upper side of the contents of the latter. A portion of the vapors will be guided by the deflector 36 between the shelves of adjacent pairs, insuring the baking of the lower portions of the contents of the upper shelf and the upper portions of the contents of the lower shelf.

The improved oven has the further advantage of providing for this increase of capacity without necessitating any increase in the floor space occupied.

I claim as my invention:

1. In a bake oven, in combination, a casing, a horizontal shaft pivotally mounted within the casing, a reel mounted on the shaft and comprising a pair of end elements, shelves arranged in vertically dispose-d pairs pivotally mounted on the reel, a side Wall of the casing parallel with the axis of the reel being provided with an inwardly inclined deflector for directing ascending vapor currents inwardly between the shelves of an ascending pair.

2. In a bake oven, in combination, a casing having a side Wall, a horizontal shaft parallel to said wall pivotally mounted within the casing, a reel mounted on the shaft and comprising a pair of end elements, shelves arranged in vertically disposed pairs pivotally mounted on the reel, and means comprising a plate extending from an upper portion of said wall for deflecting ascending vapor currents between the shelves of passing pairs.

3. In a bake oven, in combination, a casing, a revoluble reel within the casing, shelves carried by the reel and arranged in pairs, means for directing hot vapors peripherally as to the reel by convection, and means spaced from the first means for directing the hot vapors between the shelves of the several pairs.

4. In a bake oven, in combination, a casing inclosing a baking chamber, a burner in the lower part of the chamber, a reel in the chamber, a pair of vertically spaced shelves carried by the reel, and deflecting means carried by one of said shelves for directing vapors from the burner between the shelves.

5. In a bake oven, in combination, a casing inclosing a baking chamber, a burner in the lower part of the chamber, a reel in the chamber, pairs of vertically spaced shelves carried by the reel, and deflecting means carried in part by a wall of the casing and in part by certain of the shelves for directing vapors from the burner between the shelves of the several pairs.

6. In a bake oven, in combination, a casing inclosing a baking chamber, a reel within the chamber, shelves carried by the reel for supporting articles to be cooked, a combustion chamber below the reel, a flue leading from such chamber along a wall of the casing and discharging into the baking chamber in the vicinity of a horizontal plane through the axis of the reel, and deflector plates projecting outwardly from certain of the shelves and extending into the path of the vapors issuing from the flue as such shelves move though the zone of the baking chamber adjacent the discharge end of the flue.
